hey guys

the coil packs seem to be stuck in ??

i tried pulling them out with a tiny bit of force, not game enough to use more force.

for some reason they dont seem to want to come out

anyone have the same issue

would also like the answer to this as im trying to change mine this weekend

cheers

I just changed mine after reading this thread, very helpful!

You'll need a 16mm deep socket for the spark plugs, a 3" or more extension will help out as well.

well changed them yesterday, everthying was going sweet untill i overtightned one and cracked the ceramic. but after driving around everywhere trying to find iridiums was a PITA. then getting someone to gap to .8 all good now. just a quick question i bought BCPR5EIX-11 gapped to .8mm now everywhere i went asking for one they all told me i shouldnt be running them gapped to .8 bla bla bla 1.1 is sufficient. what you guys reckon?

Great post... what plugs are people suggesting for our stagea's?

What I have found looking around so far:

BCPR5EIX-11

NGK iridiums to suit rb20det

Spark Plugs - NGK BCPR7ES (copper, gapped to 0.8 mm)

Spark plugs (high speed) = NGK BCPR7ES (copper, gapped to 0.8 mm) ~$20 per set of 6.

Low speed = 1 range hotter, traffic = 2 ranges hotter.

NGK PFR5G-11

Step 4. Disconnect the loom plug (may vary in appearance). Then just move 2 disconnected looms off to the side. You don't have to remove the 2 circled screws.

How do you disconnect the the loom plug? I can't get it off and I don't want to break anything!

Also, do you have to remove the piping (for the cold air) that runs over the head to get to the spark plugs? The pictures do not show a top view shot of the engine bay with the "Nissan" cover off. Or do you simply slide it out underneath the piping?

0.8 is fine ive gone smaller depending on condition of ur coilpacks, i would never run 1.1 unless i have a beefed ignition sys. otherwise ull find it will mis under higher boost levels 15psi plus on stock 15year old coils.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
